MIC2184  
Low Voltage Buck PWM Control IC  
General Description  
Features  
Micrel’s MIC2184 is a high efficiency PWM buck control IC.  
With its wide input voltage range of 2.9V to 14V, the MIC2184  
can be used to efficiently step voltages down in 1- or 2-cell Li  
Ion battery powered applications, as well as in fixed 3.3V, 5V,  
or 12V systems.  
• Input voltage range: 2.9V to 14V  
• >90% efficiency  
• Oscillator frequency of 400kHz  
• Frequency divide-by-two pin  
• Frequency sync to 600kHz  
• FrequOut oscillator output allows simple charge pump  
implementation in low voltage systems  
• 1.245V reference output  
Efficiencies over 90% are achievable over a wide range of  
load conditions with the MIC2184’s PWM control scheme.  
The operating frequency can be divided by two by raising the

• 5Ω output driver  
versus board space. It also allows the MIC2184 to be exter-  
• Soft start  
nally synchronized to frequencies below its nominal 400KHz.  
• PWM current mode control  
• 1µA shutdown current  
The MIC2184 features an oscillator output, FreqOut, which  
can be used to implement a simple charge pump in low  
voltage applications. The output of the charge pump can be  
• Cycle-by-cycle current limiting  
• Frequency foldback short circuit protection  
• Adjustable under-voltage lockout  
• 16 pin narrow-body SOIC and QSOP package options  
fed into the gate drive power circuitry via the V P pin,  
IN  
allowing enhanced gate drive, hence higher efficiencies,  
despite low input voltages.  
Applications  
MIC2184 features a 1µA shutdown mode, and a program-

applications.  
• 3.3V to 2.5V/1.8V/1.5V conversion  
• DC power distribution systems  
• Wireless Modems  
The MIC2184 is available in 16 pin SOP and QSOP package  
options with a junction temperture range range from –40°C  
to +125°C.  
• ADSL line cards  
• 1-and 2-cell Li Ion battery operated equipment
